SNMP protocol in Logic Machine

[Carlos Padilla]

Hi Admin, thanks for replying. Use the code you told me, but it's not working. I have attached the code adapted to my OID and my IP together with an error log. I have made several modifications but none of them work for me. Thank you and I am attentive to your comments.

Code:

val=event.getvalue()
--Abrir una sesión con snmp
require('snmp')

conn, err = snmp.open({
  version = snmp.SNMPv1,
  community = 'public',
  peer = '192.168.1.248',
})

if conn then
  res, err = conn:set({
    {
      oid = '1.3.6.1.4.1.1248.4.1.1.2.1.0',
        value = '0',
    }
  })

  if err then
    alert('snmp set failed: ' .. tostring(err))
    log (err)
    log ('snmp set failed')
  else
    alert('snmp set ok')
    log ('snmp set ok')
  end

  conn:close()
else
  alert('snmp connection failed: ' .. tostring(err))
  log ('snmp connection failed')
end
